2. Should everyone have a ZPP test?

No. This test will only be done for adults with suspected chronic exposure to lead, as a screening test to detect iron deficiency in children, or occasionally to test for a porphyria that affects the skin.

3. If I have a hobby such as stained glass working but no symptoms, do I need to have a ZPP test done?

Talk to your healthcare provider about this. If the hobby is a frequent activity, then it may be recommended that you have a ZPP test and a lead test to evaluate your lead exposure. You can have an increased ZPP level with few to no symptoms or you may have symptoms that have not yet been linked to lead exposure.
